Last week I bought a 2003 Suburban 1500 4WD with 215K on it. One owner, had a mechanic do all of his maintenance.

Before I did anything, it had a soft pedal. The old pads still had some meat on them but I went ahead and replaced them anyway. I replaced both front and rear brake pads (truck has 4 wheel disc brakes) with high quality ceramic pads. The rotors looked fine so I didn’t have them cut.

After replacing the pads the truck still has a soft pedal. It will stop but it takes a lot of pedal travel. At no time did any of the bleeder screws get opened.
Someone told me the due to the ABS system, I should not try to bleed the system without a power machine.

I’ve read that new ceramic pads with old rotors need time to bed in. Should I remove the pads and scuff the rotors up?

Anyone have a good idea what I should try next?

Thanks

Master cyl needs r n r

 

Bleed the brakes yesterday. Found air in right front line. Peddle much better but still not as good as it could be.


Also, it seems the ABS is not working. I can stomp on the peddle and there is absolutely no pumping or cycling action. ABS dash light is not illuminated. It does come on when starting the truck so I know the light works.

 

Fixed it!!!!


Was installing new shocks, had the wheels off anyway so I was checking the hoses. Found the drivers front caliper bleeder screw had some debris in the screw, it didn't close completely. There was a slight leak. I tightened it and topped off the fluid. Got a nice firm pedal now
